MARK Marshall is a City doubt for the return to his former club Port Vale on Saturday.

The in-form winger suffered a tight hamstring against Bolton and the Bantams are keeping an eye on his progress ahead of the weekend.

Stuart McCall said this afternoon: “It’s not a major problem and Marshy is improving all the time.

“He’s got a good chance but with games coming thick and fast again, it’s not something we will take a risk with.

“But we’ll keep monitoring him before we make any decision.”
